I am looking to plant hydrangeas pan bobo behind a mini hedge of boxwood green velvets. Should I elevate the soil for the hydrangeas so that they stand out more? I worry if I plant everything at the same height the boxwood hedge will simply hide too much of the plant. What do you think?
Thanks!
If you're growing the boxwood as hedging, then presumably it will be a low, clipped hedge - left to grow naturally, these shrubs will reach between 2 and 4 feet, with a similar spread, so it depends how tall you let the boxwoods grow in terms of how much you will see of the hydrangeas.
The hydrangea you mention gets 3-4 feet in height, with a spread of 6 feet or more. Because hydrangeas don't like soil that dries out frequently or easily, raising the level at which you plant them isn't a good idea because the raised soil will dry out quicker than the surrounding soil. So as long as you keep the boxwoods short, optimally at 1 foot, 1.5 feet max, you will be able to see the hydrangea flowers.
To ensure your Hydrangea paniculata 'Bobo' stands out behind the boxwood hedge, slightly elevating the planting area can be a great idea. By raising the soil level by 10–15 cm (4–6 inches) and forming a gentle slope, you can enhance the visibility of your hydrangeas while improving drainage, which they prefer. Use a rich, well-draining soil mix for the raised area to promote healthy growth.
When planting, position the hydrangeas at least 60–90 cm (2–3 feet) behind the hedge, depending on the mature size of the boxwood and the hydrangeas. This spacing will ensure proper air circulation and prevent crowding. Over time, as the plants grow, their height and the elevated soil should naturally create a layered effect, showcasing the hydrangeas beautifully above the hedge.
Happy planting! 😊
